CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims benefit of priority to U.S. Provisional Patent Application Ser. No. 62/295,243, titled “Fillable Pillow,” filed Feb. 15, 2016, which is incorporated by reference herein in its entirety.

BACKGROUND

This specification relates generally to support devices. More particularly, the disclosure pertains to pillows that are adjustable by a user.

Pillows are often used to support a head or other parts of a user's body during sleeping or resting. For example, pillows may be employed while sleeping on a bed or resting on a couch or chair. Pillows typically consist of a sealed fabric envelope having a soft stuffing or filling therein, such as down feathers or synthetic foam. The fabric envelope is typically covered with a pillowcase made of a cloth material.

Experts agree that the use of an appropriate pillow for sleeping is critical for good health. An incorrectly sized or shaped pillow may cause or exacerbate headaches, neck pain, arm numbness, breathing problems and/or sneezing.

Ideally, a pillow should help keep a user's head in a neutral alignment, where the user's head is positioned squarely on their shoulders—without bending back too far or reaching too far forward. A back sleeper requires a thinner pillow, so their head is not pushed too far forward. A side sleepers needs a firmer pillow to fill in the distance between their ear and shoulder. And a stomach sleeper may require a very thin, almost flat pillow for proper head alignment.

Unfortunately, conventional pillows are not adjustable. The fabric envelope is typically sealed such that a user may not access the filler material contained therein. Accordingly, a user of these pillows may need to purchase a new pillow if they change their sleeping position preference any time after a pillow purchase. Moreover, the filler material in conventional pillows may flatten, wear or weaken over time, resulting in a pillow that lacks proper support.

There is therefore a need for an adjustable pillow that allows for a user to add or remove an amount of internal filling to increase or decrease the size of the pillow, or adjust the shape thereof. It would be beneficial if such a pillow allowed for easy, yet secure, opening and closing of an inner container that holds a filler material.

SUMMARY

In accordance with the foregoing objectives and others, exemplary adjustable pillows are disclosed herein. The adjustable pillows are adapted to hold a variable amount of filler material, the amount adjustable by a user such that the shape and/or size of the pillows may be manipulated as desired or required.

The pillow may include an inner cover disposed within an outer cover. Accordingly, the outer cover may include an aperture, or opening, sized to allow the insertion and/or removal of the inner cover therewithin. The aperture may be closed by a fastening mechanism, such as a zipper. The pillow may further include a filler material disposed within the inner cover and the inner cover may include an aperture sized to allow the insertion and/or removal of such filler material. The inner cover aperture may be closed by a fastening mechanism, such as a zipper. The pillow may comprise various sizes to conform to the body of an individual using the pillow.

In one embodiment, an adjustable pillow is provided. The adjustable pillow may include an outer cover having a plurality of panels joined to form an outer surface, an inner surface and an interior compartment sized to house an inner cover therein. The outer cover may also include a closable aperture extending from the outer surface to the inner surface along one or more of the panels, where the aperture is sized to receive the inner cover therein. A fastening mechanism may be present on the outer cover and such fastening mechanism may be adapted to allow a user to open the aperture for insertion of the inner cover into the interior compartment and/or securely close the aperture such that the inner cover remains within the interior compartment during use. The adjustable pillow may further include an inner cover disposed within the interior compartment of the outer cover. The inner cover may include: a plurality of panels joined to form an outer surface, an inner surface and an interior compartment sized to house an amount of a filler material therein; a closable aperture extending from the outer surface to the inner surface along one or more of the panels, the aperture sized to receive the filler material therein; and/or a fastening mechanism in communication with the aperture. The fastening mechanism may be adapted to allow a user to open the aperture for insertion of the filler material into the interior compartment of the inner cover; and/or securely close the aperture such that the filler material remains within the interior compartment during use.

The details of one or more embodiments of the subject matter of this specification are set forth in the accompanying drawings and the description below. Other features, aspects, and advantages of the subject matter will become apparent from the description, the drawings, and the claims.

DETAILED DESCRIPTION

Various adjustable pillows are disclosed herein that allow for addition and/or removal of a filler material within an inner cover thereof, such that the shape and/or size of the pillow may be adjusted as desired or required by a user. The adjustable pillow comprises an inner cover having a fastening mechanism to allow the inner cover to be opened and closed by a user. For example, a user may access the inside of the inner cover by unzipping a zipper present on at least one side thereof. The user may then add or remove a filler material, such as but not limited to shredded memory foam, latex noodles, and/or poly-fill foam or beads. The adjustable pillow may further comprise an outer cover having the inner cover seated therein and adapted to protect the inner cover. It will be appreciated that the adjustable pillow may be used with or without a pillow cover (i.e., the adjustable pillow may be covered by a standard or custom-sized pillow cover).

Referring to FIGS. 1A and 1B, top and bottom perspective views of an exemplary adjustable pillow 100 are illustrated, respectively. As shown, the pillow comprises an outer cover 110 with a fastening mechanism 117. The outer cover 110 may comprise a single piece of material or may comprise a plurality of panels of material connected via stitching 118 or the like.

In one embodiment, the outer cover 110 comprises an upper panel 111 connected to a lower panel 112 to form a housing. The upper panel and lower panel may each comprise a rectangular shape, with two longer sides and two shorter sides. As shown, the upper and lower panels may be connected to each other via stitching or the like 118 along both longer sides and at least one of their shorter sides. The remaining shorter sides of the upper panel and the lower panel may be connected via an openable fastening mechanism 117.

The outer cover 110 may comprise a length and width to provide an adjustable pillow having dimensions consistent with that of a conventional bed pillow (i.e., rectangular or square). For example, the outer cover may comprise an upper panel and a lower panel, each having a width of from about 20 inches to about 30 inches and a length of from about 20 inches to about 40 inches. Specific embodiments of the outer cover 110 may comprise a width of about 20 inches and a length of about 26 inches (i.e., standard size); a width of about 20 inches and a length of about 30 inches (i.e., queen size); a width of about 20 inches and a length of about 36 inches (i.e., king size); and/or a width of about 26 inches and a length of about 26 inches (i.e., European size).

Generally, the outer cover 110 defines a housing with an interior compartment adapted to hold a volume of from about 1,000 cubic inches to about 5,000 cubic inches, for example about 1,820 cubic inches, about 2,100 cubic inches, about 2,366 cubic inches or about 2,520 cubic inches. The volume may also vary based on the elasticity of the fabric of the outer cover 110 and/or on an amount of filler material contained within the adjustable pillow 100. As discussed in detail below, the outer cover 110 may be adapted to hold an inner cover, which itself holds a volume of material.

In other embodiments, the outer cover 110 may comprise a configuration of one or more connected panels of any shape, such that the pillow comprises a shape selected from the group consisting of: oval, bolster cylindrical, rectangular box, donut-shaped, toss/throw pillow shaped, knife edge, welted or corded, box edge, body pillow and/or a sham shape.

Although not shown the outer cover 110 may comprise any number of decorative elements. For example, the outer cover 110 may include one or more flanges (i.e., fabric that extends from one or more side seams); piping (i.e., covered cord sewn into the seams as a decorate detail); fringes and/or beading attached to one or more sides thereof.

Referring to FIG. 2, the adjustable pillow 100 is illustrated with the outer cover fastening mechanism 117 in an open position. As shown, an inner cover 120 is disposed within an interior compartment of the outer cover 110.

As shown, the outer cover 110 may comprise an aperture 119 extending from an outer surface of the outer cover 110 to an inner surface thereof. The aperture 119 is sized such that an inner cover 120 may be inserted into and/or removed from an interior compartment of the outer cover 110 via the aperture 119.

The outer cover 110 comprises a fastening mechanism 117 adapted to allow the aperture 119 of the outer cover 110 to be opened, such that an inner cover 120 may be inserted into the interior compartment of the outer cover 110. The fastening mechanism 117 is further adapted to allow the aperture to be closed in order to maintain the inner cover 120 securely within the interior compartment of the outer cover 110. In one embodiment, the fastening mechanism 117 is a zipper. In other embodiments, the fastening mechanism may be selected from the group consisting of: zippers, snaps, buttons, straps, hook and loop fasteners, and combination thereof.

The aperture 119 and fastening mechanism 117 may be located anywhere along the surface of the outer cover 110. In one embodiment, the aperture 119 is located along an edge of a single side of the outer cover 110 (i.e., between an upper panel and a lower panel). For example, the aperture 119 may be located along one of the shorter sides of a rectangular-shaped outer cover. Such an aperture may extend a length of from about 20 inches to about 36 inches, for example about 26 inches, depending on the length and/or width of the outer cover.

Although the aperture is shown as being present on a single side of the outer cover, it will be appreciated that, in other embodiments, the aperture may extend along a longer side of a rectangular-shaped outer cover or along multiple sides thereof. Alternatively or additionally, an aperture may be located along a single panel, away from the outer cover edges.

In one embodiment, the outer cover 110 may not comprise a fastening mechanism. In such an embodiment, the outer cover may overlap itself at or near the aperture, providing a finished appearance to the outer cover.

The outer cover 110 may be adapted to protect the inner cover 120 from wear and tear, environmental elements (bacteria, moisture, dirt, pollen, pollutants and other allergens, etc.) and/or to provide a comfortable feel to a user (with or without an additional pillowcase surrounding the outer cover). To that end, the outer cover 110 may comprise one or more materials selected from the group consisting of: cotton, silk, satin, leather, microfiber, bamboo, rayon (e.g., viscose rayon derived from bamboo), polyester, polyurethane, and combinations thereof.

In one preferred embodiment, the fabric of the outer cover 110 comprises a blend of polyester and viscose rayon derived from bamboo. The fabric may comprise from about 20 percent to about 80 percent rayon (e.g., about 40 percent rayon) and from about 80 percent polyester to about 20 polyester (e.g., about 60 percent polyester). As a specific example, the outer cover may comprise a blended material of about 40 percent rayon (e.g., viscose rayon derived from bamboo) and about 60 percent polyester. Such a material may allow heat to distribute more evenly across the fabric and thus may contribute to even temperature regulation throughout the adjustable pillow. Moreover, such material is preferred as it is washable, hypoallergenic and dust mite resistant.

In certain embodiments, the outer cover may comprise a thickness of from about 0.01 inches to about 1 inch. For example, the outer cover may comprise a thickness of about 0.01 inches, 0.03 inches, about 0.05 inches, about 0.1 inches, about 0.5 inches, about 0.75 inches or about 1.0 inches. An appropriate thickness may be selected based on the amount and type of filler material employed.

Although not shown, the outer cover 110 may comprise a gusset disposed between the upper panel 111 and the lower panel 112 thereof. A gusset may allow expansion of the outer cover 110 such that the interior compartment may hold a larger volume. The sides of the middle panel may be stitched to the sides of the upper panel 111 and the lower panel 112. Where the sides of the upper panel and the lower panel comprise a fastening mechanism meant to allow the outer cover 110 to be opened, the sides of the middle panel may comprise complementary fastening mechanism adapted to allow a user to open an aperture between either the gusset and the upper panel or the gusset panel and the lower panel.

Referring to FIGS. 3, 4A, and 4B, the adjustable pillow 100 is shown to comprise an inner cover 120 shaped to hold a filler material 130 within an interior compartment thereof. The inner cover 120 is further shaped to be placed within the interior compartment of the outer cover 110.

The inner cover 120 may comprise a single piece of material or may comprise a plurality of connected sections or panels of material. In one embodiment, the inner cover 120 comprises an upper panel 121 connected to a lower panel 122 along the edges thereof to form a housing or interior compartment. The upper panel and lower panel may each comprise a rectangular shape, with two longer sides and two shorter sides. As shown, the upper and lower panels may be connected to each other via stitching or the like 128 along both longer sides and one of their shorter sides. The remaining shorter sides may be connected via an openable fastening mechanism 127.

The inner cover 120 may comprise a length and width substantially similar to that of the outer cover 110. For example, the inner cover 120 may comprise an upper panel 121 and a lower panel 122, each having a width of from about 20 inches to about 30 inches and a length of from about 20 inches to about 40 inches. Specific embodiments of the inner cover may comprise a width of about 20 inches and a length of about 26 inches; a width of about 20 inches and a length of about 30 inches; a width of about 20 inches and a length of about 36 inches; and/or a width of about 26 inches and a length of about 26 inches.

Generally, the inner cover 120 defines a housing with an interior compartment adapted to hold a volume of from about 1,000 cubic inches to about 5,000 cubic inches, for example about 1,820 cubic inches, about 2,100 cubic inches, about 2,366 cubic inches or about 2,520 cubic inches. Like the outer cover 110, the volume of the inner cover 120 may also vary based on the elasticity of the fabric of the inner cover 120 and/or on an amount of filler material contained within the inner cover 120. As discussed in detail below, the inner cover 120 may be configured such that its interior compartment is adapted to hold an amount of filler material.

In other embodiments, the inner cover 120 may comprise a configuration of one or more connected panels of any shape and/or size, including but not limited to rectangular, square, circular, oval, triangular, etc. It will be appreciated that the inner cover may comprise a shape that is substantially similar to the outer cover. However, in alternative embodiments, the inner cover may comprise a different shape from that of the outer cover.

The inner cover 120 may comprise an aperture 129 extending from an outer surface of the inner cover to an interior compartment thereof. The aperture 129 is sized such that a filler material 130 may be inserted into and/or removed from an interior compartment of the inner cover 120 via the aperture 119. Accordingly, the aperture may extend a length of from about 20 inches to about 36 inches.

The inner cover 120 comprises a fastening mechanism 127 adapted to allow the aperture 129 of the inner cover 120 to be opened, such that filler material 130 may be inserted into the interior compartment of the inner cover 120. The fastening mechanism 127 may be further adapted to allow the aperture to be closed in order to maintain the filler material 130 securely within the interior compartment of the inner cover 120. In one embodiment, the fastening mechanism 127 is a zipper. In other embodiments, the fastening mechanism may be selected from the group consisting of: zippers, snaps, buttons, straps, hook and loop fasteners, and combination thereof.

The aperture 129 and fastening mechanism 127 may be located anywhere along the surface of the inner cover 120. In one embodiment, the aperture is located along an edge of a single side of the inner cover 120 (i.e., between an upper panel 121 and a lower panel 122). For example, the aperture 129 may be located along one of the shorter sides of a rectangular-shaped inner cover.

In other embodiments, the aperture 129 may extend along a longer side of a rectangular-shaped inner cover, or along multiple edges thereof Alternatively or additionally, an aperture may be located along a single panel, away from the inner cover edges.

The inner cover 120 may be adapted to protect the filler material 130 from wear and tear, environmental elements (bacteria, moisture, dirt, pollen, pollutants and other allergens, etc.) and/or to provide a comfortable feel to a user (with or without an additional pillowcase surrounding the outer cover). To that end, the inner cover 120 may comprise one or more materials selected from the group consisting of: cotton, polypropylene, polyethylene, wool, silk, satin, bamboo, polyester, polyurethane, rayon and combinations thereof. In one preferred embodiment, the inner cover 120 comprises 100 percent interlock polyester.

Although not shown, the inner cover 120 may comprise a gusset disposed between the upper panel 121 and the lower panel 122 thereof. A gusset may allow expansion of the inner cover 120 such that its interior compartment may hold a larger volume of filler material. The sides of the gusset may be stitched to the sides of the upper panel 121 and the lower panel 122. Where the sides of the upper panel 121 and the lower panel 122 comprise a fastening mechanism meant to allow the inner cover 120 to be opened, the sides of the gusset may comprise a complementary fastening mechanism adapted to allow a user to open an aperture between either the gusset and the upper panel or the gusset and the lower panel.

As shown in FIG. 3, a filler material 130 may be inserted into and/or removed from the interior compartment of the inner cover 120 via the aperture 129. The filler material 130 may be positioned or manipulated by a user to effect the size and/or shape of separate portions of the adjustable pillow 100 and may maintain the chosen shape better than other materials during use. For example, a user may manipulate the filler material such that the pillow comprises a volume that varies along the length and/or width of the pillow (e.g., a larger volume of filler material in one portion and a smaller volume of filler material in another portion). The distribution of the filler material may be adjusted to create any regularly or irregularly shaped pillow.

In certain embodiments, the filler material 130 may comprise one or more materials selected from the group consisting of: bamboo, beanbag filler, buckwheat hulls, cotton fabric scraps, feathers, flaxseed, foam blocks, hemp, horsehair, kapok fiber, lavender, microbeads, millet, polyester, polyester pellets, polystyrene beads, polyfill, rayon (e.g., viscose rayon derived from bamboo), rice, shredded memory foam, shredded natural or synthetic latex, shredded paper material (e.g., newspaper), siliconized polyester fibers, shredded rubber, silk, water, wool and/or combinations thereof.

In one particular embodiment, the filler material 130 comprises a shredded memory foam material complying with each of the parameters specified in the October 25, 2016 CertiPUR-US Physical Performance and Environmental Guidelines for Certification of Prime Flexible Polyurethane Foam for Use in Furniture and Bedding, as found at certipur.us (incorporated by reference herein in its entirety). Such filler material may be manufactured without the following chemicals: chlorofluorocarbon (“CFC”), hydrochlorofluorocarbons (“HCFCs”) or other ozone depleters; butylated hydroxytoluene (“BHT”) polyol additives; certain flame retardants such as polybrominated diphenyl ethers (“PBDEs”), trisphosphate (“TDCPP”) and tris(2-carboxyethyl)phosphine (“TCEP”); dichloromethane (MeCl₂) or n-propyl bromide (“nPB”). Such filler material may be hypoallergenic and dust mite resistant.

In one embodiment, the filler material 130 may comprise a plurality of shredded material and may be shaped so as to leave air space between the individual shredded pieces of the filler material. This may aid in improving breathability throughout the adjustable pillow 100 and may prevent the adjustable pillow 100 from retaining unpleasant odors. In other embodiments, the filler material 130 may comprise: a hypoallergenic material, a flame-retardant material, a moisture-wicking material, an insect repellent material, a temperature-regulating material and/or combinations thereof.

Referring to FIGS. 5A-5C, an exemplary adjustable pillow 500 is shown with various amounts of filler material contained therein. In order to adjust the adjustable pillow to meet the needs of the user, a filler material may be added to, or removed from, an inner cover of the adjustable pillow. For example, a height hl and/or volume of the adjustable pillow 500 may be increased to suit the needs of a user who sleeps on his/her side (FIG. 5A). As another example, a height h2 and/or volume of the adjustable pillow 500 may be decreased (i.e., by removing an amount of filler material) to suit the needs of a user who sleeps on his/her back (FIG. 5B). As yet another example, the height h3 and/or volume of the adjustable pillow 500 may be further decreased (i.e., by removing an amount of filler material) to suit the needs of a user who sleeps on his/her stomach (FIG. 5C).

Referring to FIG. 6, an alternative embodiment of the adjustable pillow 600 is shown where an outer cover 610 houses a first inner cover 620 and a second inner cover 670. The first inner cover 610 may house a first filler material 640 and the second inner cover 670 may house a second filler material 650. The first filler material 640 and the second filler material 650 may be the same material or may be different materials. Including multiple inner covers to hold different filler materials (or different amounts of filler materials) may increase the modularity of the adjustable pillow and may allow a user to create a fully adjustable pillow customized for the user's specific needs.
